There are 2 things I'm happy to spend time on here:
1)Answering people's questions/requests
2)Telling people that they don't deserve to be answered yet
In that case you fell into #2, however, now with a much better question, I'm going to answer under #1.
To know how we are different, it would be great to know what you are looking for. Some people want fast downloads for their downloaders, others want upload management tools, others want high PPD rates, others want high referral rates.
So depending what you want, we have something to offer. I believe the biggest thing is that, because of our experience with server admin and web development, we have created a world-class file hosting system. Yes, the script is XFS but the script is only 25% of the site. The other 75% is the server setup. We have invested significant time and money getting our server setup correct so that we can maintain our reliability and download speeds.
